Be it known that I, Mansion H. Ronnnrrs,

a citizen of the United States, residing at Boston, county of Suffolk,Stateqof Massachusetts, have invented a certainnew andu'sefulImprovement in Egg Beaters, ofv

which the following is a specification, reference being had therein tothe accompany 'ing drawings. I v

The present lnvention'relates to egg beaters of the rotary type havingashaft with blades which rotate with the shaft. ()ne ob iect of thepresent invention is to improve this type of egg beater by combiningwithlt a dash which is operated at the same time that the blades arerotated. Another feature of the invention relates to theform of theblades.

'The invention will be fullyunderstood from the following descriptionwhen taken.

in connection with the accompanying draw ings and the novel. featuresthereof will be pointed out and clearly defined in the claims at theclose of this specification.

In the drawings, Fig. lis a view in elevation partly in section of adevice embody ing the invention. I

- Fig. 2 is a section on line 2-2 of Fig. Fig. 3 is a section on line3-3 of Fig. Fig. 4 is a section on line ti of Fig. Fig. 5 is a sectionon line 5+5 of Fig.

Referring nowv to thedrawings, at 10 is shown a handle whichis formedwith. a

socket to receive the shaft ll and'aspring 12, one end of which isseated in-the upper end -of the socket of the liandle andthe other.

end of which s sea-tedv upon a disk 18.011

' the upper. end of the shaft '11.

The shaft 11 ismade of flat rnetal twisted so that the edges are ofspiral form. Se-

curedto the'lower end of thehandlelO is a thimble 14 formed withelongated slot 15 in its lower closed end through which the shaft 11passes. By resting the lower end of the shaft on a support. for instanceon the bottom of a cup which contains the egg which isto be beaten, andpressing'down on the upper end of the handle 10, the shaft will berotated in well-known manner by reason of the twisted form of the shaftand the elongated form "of the slot 15. When the downward pressure uponthe handle is released the spring 12 which was compressed when thehandle was pushed down will 7 disk at the lower.

carried thereby will-tend to: pitch upwards and sideways theingredientsfin the recep tacle, each propeller bla de giving an upwardtoss to the contents with which it comes .in contact as well as stirringtheni V y A plunger disk 20 which operates a dash is rigidly connectedwith the handle 10.. so as to moveup and down with the handle.Preferably this connection is made by means of rods2l2l which serveashangers, the lower ends of which are connected with the dash member 20and the upper ends of which are connected. with a disk 22 which isformed as a flange on the upper end of the thiinble Mfand thus made fastto the handle 10. The said disk QOdsform'ed with a central opening 23through which the shaft 11 freely 7 passes, so that as the handle ismoved up and down to rotate-the shaft lland the paddle end of the shaft,the said move up and down without '85 dash disk 20 will rotation. I a. vThe said disk 20 is formedwitha plurality of apertures 24 sothatwhenitis moved .up and down a portion of the contents will passthrough the said apertures. If the disk were made solid its up anddownmovement would beseriouslyin peded. I The apertures; however, affordsufiici entvent so that the up and down movement of the disk'20ais not"seriously impeded and a't thesame time the oontentso'f the containerwhich are-being beaten are cut to a considerable extent by reason of theforced passage through the said apertures. It will-thus be seen thatbyholding the lower end of the shaft against the bottom of the containerand reciprocating the handle 10 rapidly up and down in well-knownmannor, the stirrer blades 19 will be caused to rapidly rotate first inone direction and then in the other, stirring up the contents of thereceptacle which is at the bottom, and also by reason of the peculiarformation of the blades tossing the contents from the bottom upwards andtoward the center and at the same time the dash 20 will be moved up anddown giving a still different cutting movement to the contents.

The blades 19 act very much like a whirling. propeller which throws theingredients to the center of the receptacle as well as up, and they arethen caught by the dasher with an up-and-down motion that forces airinto the ingredient and converts it into a smooth, light and frothysubstance.

It is very useful for whipping cream, beating eggs, omelettes, Custards,malted milk, and all kinds of drinks and mixtures. Therefore, while Ihave for convenience re ferred to the device as an egg beater, I wish itto be understood that the claims are intended to cover the devicewhether used strictly as an egg beater or for any other purpose forwhich it is adapted.

What I claim is 1. An egg beater having a rotary shaft provided with aseries of laterally extending paddles on its lower end, a verticallymovable dasher mounted above the said paddles through which the saidshaft loosely passes, and means for rotating the said shaft and paddlesfirst in one direction and then reversing the direction of rotationandsimultaneously reciprocating the dasher up and down, the dasher beingat all times entirely a above the paddles.

2. An egg beater having a rotary shaft provided with a series oflaterally extending paddles on its lower end, a vertical handle having asocket into'which the upper end of said shaftextends, a spring in saidsocket on which the upper end of said shaft is seated, means wherebywhen the lower end of said shaft is raised on its support and saidhandle is reciprocated up and down, the said shaft will be rotated firstin one direction and then in the other, and a plunger disk mounted onsaid handle, said disk being apertured-for the passage ofthe shaft,whereby as the handle is operated to actuate the rotary shaft the saidplunger, will also be reciprocated' up and down, said plunger diskbeingformed with a plurality of apertures.

8. An egg; beater having a rotary worm shaft provided with a pluralityof radiating blades secured to its lower end, a plunger handle having alongitudinal socket in which the upper end of the shaft is received, aspring in the upper part of said socket on which the upper end of theshaft is seated, the handle being provided at its lower end with aslotted entrance to said socket through which the shaft passes, saidslot being so shaped with relation to the shaft that as the handle isvertically reciprocated while the lower end of the shaft rests on abottom support the shaft will be rotated alternately in oppositedirections, a disk rigidly suspended from the lower end of the handle insuch manner that the disk is at all times some distance below thelowerend of the handle and above the rotary blades at the lower end ofthe shaft, the shaft passing loosely through a hole in the disk so thatthe disk can move freely up and down with the operation of thehandlesimulta neously with the rotation of the blades.

at, An egg beater having a rotary worm shaft provided with aplurality'of radiating blades secured to its lower end, a plunger handlehaving a longitudinal socket in which the upper end of the shaft isreceived, a spring in the upper part of said socket on' which the upperend of the shaft is seated, the handle being provided at its lowerendwith a slotted entrance to said socket through which the shaft passes,said slot being so shaped with relation to the shaft that as the handleis vertically reciprocated, while the lower end of the shaft rests on abottom support, the shaft willbe rotated alternately in oppositedirections, hangers secured to the lower end of the handle and rigidlysupporting at their lower ends, a disk which is thus suspended at somedistance below the lower end of the handle and above the rotary bladeson the lower end of the shaft, said disk being non-rotatal'ile, thesaidshaft passing loosely through a hole in the disk so that the diskcan move freely up and down with the handle and. with re'-' lation tothe blades, said disk being reciprocated by the reciprocating movementof the handle simultaneously with the rotation of the blades. 7 V v Intestimony whereofl affix my signature.
